QUESTION: Recently, reviewers have denied diagnostic code 584.9 (acute renal failure [ARF]) based on lab values. The diagnosis is well documented and treated by the attending physician, but reviewers are stating the lab values do not support the diagnosis of ARF. The lab values (creatinine/blood urea nitrogen) went from normal to abnormal, and we found no definitive standards for lab parameters to meet the definition of ARF. Following coding guidelines for reporting secondary diagnoses, the ARF was clinically evaluated, the patient received therapeutic and diagnostic procedures, and there was an extended length of stay/increased nursing care. As coders, we feel it is inappropriate to question the physician’s clinical judgment, and reporting the ARF as a secondary diagnosis is correct. Based on the documentation in the record, is it appropriate to code the ARF?
QUESTION: Can a patient have encephalopathy after surgery? For example, a patient becomes confused post-surgery and is transferred from the medical-surgical floor to the intensive care unit, where he or she receives high doses of pain medication via IV. However, the patient recovers well and the confusion disappears after the IV fluids and reduction in pain medication and oxygen. Would it be appropriate to query the physician regarding encephalopathy and its possible cause, or would this be a red flag for auditors? The situation did extend the patient’s length of stay by one day.
QUESTION: We have a question in regards to hydration that we are trying to figure out. Does the physician specifically have to state in his or her documentation that the IV is for hydration purposes or can a coder figure it out through critical thinking and using the process of hierarchal injection/infusion coding when reading the record? For example, X IV fluids are being used for an antibiotic and after the antibiotic, the IV fluids continue at 125/hr for hydration. Does the physician need to document "for hydration"? Our physicians do not want to write that. Do you have any good advice on this?

The Office of the Inspector General (OIG) stated in its recent publication, “Hospital Incident Reporting Systems Do Not Capture Most Patient Harm,” that a series of reports examining adverse events in hospitals shows that for the hospitals it surveyed, the incident reporting systems only tracked approximately 14% of incidents.
